I found this on the Cabrillo Festival website which regularly performs Kevin Puts' music and find this performance of Symphony No. 2 (Marin Alsop/Cabrillo Festival Orchestra) more intense and raw than the same conductor with the Peabody Orchestra on Naxos.
http://cabrillomusic.org/kevin-puts-work-samples/I was in the audience for this recorded performance and at around twelve minutes in we were entirely spellbound by the gradually unfolding cacophony that culminated with these devastating crunches in the pedal bass trombone register which you could feel hit you like a concussion grenade. Listen to this music very loud so it approximates the live experience where the chaotic moments are truly terrifying and the still moments mesmerizing. Unfortunately, these recordings are MP3 so lose some frequencies and presence that is truly in the music.
